Comment 3 for bug 925957

My assumption was just based on the (poor) visual performances and the
"Unknown" tag (shown on the System Info) that I mistakenly associated to
the graphic card.
I didn't think that the display could have been a factor on the
performances but, as you say, the system couldn't identify the exact model
of the monitor then probably the troubles are coming from there.
So you're right, "[RS690M] Wrong monitor identified in EDID" is a more
accurate description.

Thanks for your help :)
